Signature Aggregation

Definition ∞ Signature aggregation is a cryptographic technique that combines multiple digital signatures into a single, compact signature. This process allows a group of signers to produce one verifiable signature representing all individual authorizations, rather than requiring each signature to be validated separately. It significantly reduces the data size required for transaction verification, improving blockchain scalability and efficiency. Schnorr signatures are a prominent example of a scheme enabling this advanced cryptographic functionality.
Context ∞ Signature aggregation is a key topic in news regarding blockchain scaling solutions, particularly for networks seeking to increase transaction throughput and reduce data footprint. Its implementation is often discussed in relation to protocol upgrades and proposals aimed at enhancing network capacity and lowering transaction fees. The technology holds significant promise for improving the performance of multi-signature transactions and batch processing on decentralized ledgers.
